Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bahmni

  • The licence is free and the implementation is not; configuration, data migration, training and multi-year support from a partner routinely cost far more than a small commercial system would have, and hospitals that budget only for hardware stall.
  • There is no single vendor with an obligation to you unless you contract one, so upgrade timing, security patching and defect resolution depend on whichever partner you hired and how long they stay engaged.
  • It integrates four substantial open source systems, which means an upgrade touches OpenMRS, OpenELIS, Odoo and the imaging stack together, and hospitals with heavy customisation often freeze on an old version rather than risk it.
  • Skilled Bahmni implementers are concentrated in a small number of firms in India and a few African countries, so a hospital outside those markets may find nobody local who can support it.
  • Funding for the coalition and its shared engineering comes from donors and member contributions rather than licence revenue, which makes the pace of core development dependent on grant cycles rather than on customer demand.

Calm

  • Free tier is severely limited, with almost all content requiring payment
  • Only one meditation per day included in free tier (Daily Calm)
  • Annual pricing is among the highest in the meditation app category
  • Less extensive free content library compared to Insight Timer (which has 100,000+ free meditations)
  • Limited customization of meditation sessions; mostly follows Calm's curated content
